� Forced Motor CoolingAs illustrated, a part of pumped fluid flows in between the outer cover and the motor housing before being discharged, thus cooling the motor on its way. This forced motor cooling construction assures the pump of long and continuous operations even exposed to air.

� Side Flow DesignThe side flow design not only makes the pump easier to install in narrow locations but also keeps the motor cooling forcibly even if the pump is oper-ated continuously with its motor exposed to air.

� Spiral DesignThe spiral design allows fluids containing slur-ry, sand, or mud to pass through smoothly.

� AgitatorThe agitator installed on the motor shaft extension forcibly agitates the fluid for easy and efficient transfer of slurry, sand, or mud.

Innovations that ensure high durability and superb wear resistance HSDSingle-phase portable pump fit for use in slurry dewatering in foundation works.

Uses chromium iron casting for the impeller and agitator.
